Spring Style Tip: Add a Middle Layer

For a casually rugged touch, insert a warm outer layer between your shirt and sport coat.

To add a rakish accent—and some extra warmth—to a run-of-the-mill shirt, tie, and jacket ensemble, slip on a bright vest as the meat in your sartorial sandwich. Just make sure it's short, lightweight, and features high arm holes. Speaking of rakish accents, a tie bar and a pocket square are worth considering, too.
